I think you guys are considering only the easy cases. My job's source
tree has 100K or so nodes, and it takes well over half an hour to stat
them over AFS over a cable modem.

That said, we use CVS, and we're not about to run out and use Perforce
for fast crawl capability. Getting a list of modified files in my whole
working dir quickly would be nice sometimes, but usually I'm working in
a small subset of the tree.

If we already have read-only checkouts because we want to provide locks,
then fast crawl is probably reasonable to support (not too much
complexity for the benefit). But it's definitely not a 1.0 feature.
